Application filed April 23, 1925.

To all whom it may concern:

Be it known that I, Ewnili) Konnnnn, a citizen of the Republic of Germany, residing at Dresden, Germany, have invented new and useful In'iprovcme-nts in Cigarette ltfachines, of which the following is a specification.

This invention relates to improvements in cigarette machines, and particularly to the knife-driving mechanism for such machines, the principal object of the invention being to provide improved means for rotating the knife by the action of the crank ordinarily employed for operating the knife carrier.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention consists in the novel features of construction and combination. of parts which will be more fully described hereinafter and particularly pointed out in the claims.

The drawing accompanying and forming part of this specification is a side elevation of a knife carrier embodying the features of the present invention.

Referring to the drawing, 1 designates the usual knife carrier having aknife 2 secured at one end of a shaft which is mounted for rotation in the carrier, said shaft carrya bevel pinion 3 at its opposite end. The carrier is in turn pivotally carried on crank arms 4, 4; which are secured to shafts 5, 5 mounted for rotation in bearings 6 on the frame of the machine, one of said shafts being the carrier driving shaft. At the rear of the carrier a sleeve bearing 7 is provided at right angles to the knife shaft, in which sleeve is mounted for rotation a stud shaft carrying at each end thereof a bevel pinion, the upper one 8 of which is in. mesh with the pinion 3 on the knife shaft. The other pinion 9 carried by the stud shaft is in mesh with bevel gear 10 fixedly secured on the crank pin of the crank arm l.

Motion may be imparted to the crank shafts 5, 5 from any suitable source of power. hen the sh l s are rotated so as to rotate the crank arms in the direction indicated by the large arrow at the left of the drawing the knife carrier 1 is moved downward and with it the entire system of gearing. Inasmuch as the gear 10 is Serial No. 25,205.

fixed against rotation on its own axis, its relation to the pinion 9 changes as it is moved bodily around the axis of the shaft 5 as indicated by a comparison of the relative positions of the heavy black lines on gear 10 and pinion 9 in their full-line position with the relative positions of said lines in the dotted-line position of the gears. It will thus be readily seen that as the crank shafts rotate, a forward and backward motion and a vertical motion are imparted to the carrier 1 and atthe same time rotary motion is transmitted by means of the pinions 9, 8 and 3 to the shaft of the knife so that the latter continues to rotate so long as there is any rotation of the crank shafts.

l/Vhile I have stated that the device herein described is particularly adapted for use in a cigarette machine, it is to be understood that I' do not thereby limit my invention to its use in that connection, as I am aware that it is equally applicable to any organizations in which a rotating knife is used, which knife must be intermittently carried into operating position. and which it is desirable be maintained rotating While being moved.

Having thus described my invention, what I claim is: i

1. An apparatus of the character described, comprising, in combination, a pair of crank arms mounted for rotation, a frame pivotally connected to said arms and adapted to be rotated bodily in a vertical plane, a knife-carrying shaft mounted for rotation in said frame, and gearing between one of said crank arms and said shaft for rotating the shaft when the crank arms are rotated.

2..-A.n apparatus of the character described, comprising, in combination, a pair of crank arms mounted for rotation, a frame pivotally connected to said arms and adapted to be rotated bodily in a vertical plane, a knife-carrying shaft mounted for rotation in said frame, a gear rigidly secured to one of said crank arms, and gearing between said gear and said shaft for rotating the shaft when the crank arms are rotated.

3. An apparatus of the character described, comprising, in combination, a pair of crank arms mounted for rotation, a frame pivotally connected to said arms and adapted to be rotated bodily in a vertical plane, a knife-carrying shaft mounted for rotation in said frame, a bevel gear rigidly secured to one of said crank ar1ns a stud shaft mounted for rotation on said frame, a bevel pinion secured to said knife-carry ing shaft, and a pair of bevel pinions secured to said stud shaft, one in mesh With said gear and the other in mesh with the 10 bevel pinion on the knife-carrying shaft.

In testimony whereof I have signed my name to this specification.

EWALD KOERNER.
